It can be done on the cheap.
But, you have to be tough.
My wife comes from a poor family.
She still prefers to dump buckets of cold water over her head to shower rather than use our hot shower.
She eats veggies, chili peppers and rice. Almost every day the same.
She's tough.
I've seen tougher in the jungles here in Thailand.
People who live out there with no electricity and seem to have one set of clothes that they've been wearing for years.
They don't need shoes. Make sandals out of tires.
It can be done.
Is our OP tough enough?
Maybe.
